Swordfish is an OSGi framework that makes it easy to develop enterprise services on OSGi. It provides features like runtime service discovery, security, monitoring, and remote configuration. The document demonstrates how Swordfish can be used to develop a composite FlightBooking service that orchestrates calls to separate FlightReservation and PaymentProcessing services running on different OSGi runtimes.

- 4. A few words about OSGi and some terms OSGi: A standard for creating highly modular Java applications, based on the concept of bundles. The Swordfish framework requires an OSGi runtime (usually Eclipse Equinox). Bundle: A module containing Java implementation classes and additional data that can be deployed into an OSGi runtime environment. A bundle can provide code to and use code from other bundles, allowing for better modularization. Target platform: A set of OSGi bundles that defines the runtime environment for the bundles you create in your Eclipse workspace. The Swordfish target platform contains the Swordfish framework and the plug-ins you intend to use. PDE : Plug-in development environment, the Eclipse perspective and tools you use to create bundles with the Eclipse IDE.

Notas do Editor
- SOA solution implemented on the distributed ESB pattern Theres no central hub Consumer and provider communicates directly The way in which consumer and provider speaks can be completely customizable You can have a plugin that for a svc consumer calls go to a registry and looks for policies Every aspect of swordfish can be customised by your own implementation There a re api to customise Monitoring - svc lookup Based on proven tech, Goal is to add enterprise features to the apache libraries Completely based on osgi => expandable Developing consumer and providers = develop osgi components
- PDE è il nome originario, ma serve per sviluppare bundles
- See the scenario to demonstrate the development of svcs FlightBooking svc orchestrates calls to FRS and PPS
- The interfaces are described in WSDL => generate code for providers and consumers
- Spero di avervi convinto che creare una serie di servizi con Eclipse SOA dal punto di vista dello sviluppatore è semplice: non occorre conoscere SOAP, i WS in dettaglio, ecc. E’ sufficiente concentrarsi sulla logica di buz. SOA però è molto di più, non è solo servizi. Vediamo che succede se aggiungo un service registry
- Swordfish ha delle caratteristiche che gli altri ESB non hanno
